Potential Tool Use by Wolves (<i>Canis lupus</i>): Crab Trap Pulling in Haíɫzaqv Nation Territory. [PDF]
Ecol EvolRecently, recurring damage to crab traps used by Haíɫzaqv Nation Guardians to control a European Green Crab invasion was investigated with remote cameras. A wolf was recorded emerging from the water carrying a crab trap buoy, then sequentially pulling the attached line up the beach until the initially submerged trap emerged from the water, with the ...

Steller Sea Lion (Eumetopias jubatus) Response to Non-lethal Hazing at Bonneville Dam
Frontiers in Conservation Science, 2021 Protected Steller sea lions (Eumetopias jubatus) aggregate at Bonneville Dam on the Columbia River and prey upon multiple species of endangered salmon ascending the river. Hazing is a non-lethal activity designed to repel sea lions that includes aversive

Rare Record of Albinism in a New Zealand Fur Seal (<i>Arctocephalus forsteri</i>) Pup With Observations Through the Weaning Period. [PDF]
Ecol EvolThis article provides the first known scientific record of albinism in a New Zealand fur seal pup. We describe the individual with a particular focus on its sensory abilities. This individual's birth at a central mainland colony may permit continued study throughout his life, unlike many records of similar conditions in other species.

Reduced survival of Steller sea lions in the Gulf of Alaska following marine heatwave
Frontiers in Marine Science, 2023 The North Pacific marine heatwave of 2014–2016 (PMH), one of the most geographically-extensive and severe marine heatwaves on record, resulted in widespread and persistent perturbation of the Gulf of Alaska and California Current ecosystems.

POXVIRUS INFECTION OF STELLER SEA LIONS (EUMETOPIAS JUBATUS) IN ALASKA [PDF]
Journal of Wildlife Diseases, 2005 Lesions suggestive of poxvirus infection were observed in two Steller sea lions (Eumetopias jubatus) in Alaska during live capture-and-release studies during 2000 and 2001. Both of these animals, female pups in poor body condition, were from Prince William Sound; this population is part of the declining western stock.

Survival of adult Steller sea lions in Alaska: senescence, annual variation and covariation with male reproductive success [PDF]
Royal Society Open Science, 2018 Population dynamics of long-lived vertebrates depend critically on adult survival, yet factors affecting survival and covariation between survival and other vital rates in adults remain poorly examined for many taxonomic groups of long-lived mammals (e.g.

Linking reproduction and survival can improve model estimates of vital rates derived from limited time-series counts of pinnipeds and other species. [PDF]
PLoS ONE, 2013 We propose a method to model the physiological link between somatic survival and reproductive output that reduces the number of parameters that need to be estimated by models designed to determine combinations of birth and death rates that produce ...
